<p>X509_REQ_get_extensions, X509_REQ_add_extensions, X509_REQ_add_extensions_nid - handle X.509 extension attributes of a CSR</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code>#include &lt;openssl/x509.h&gt;

STACK_OF(X509_EXTENSION) *X509_REQ_get_extensions(X509_REQ *req);
int X509_REQ_add_extensions(X509_REQ *req, const STACK_OF(X509_EXTENSION) *exts);
int X509_REQ_add_extensions_nid(X509_REQ *req,
                                const STACK_OF(X509_EXTENSION) *exts, int nid);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>X509_REQ_get_extensions() returns the first list of X.509 extensions found in the attributes of <i>req</i>. The returned list is empty if there are no such extensions in <i>req</i>. The caller is responsible for freeing the list obtained.</p>

<p>X509_REQ_add_extensions() adds to <i>req</i> a list of X.509 extensions <i>exts</i>, which must not be NULL, using the default <b>NID_ext_req</b>. This function must not be called more than once on the same <i>req</i>.</p>

<p>X509_REQ_add_extensions_nid() is like X509_REQ_add_extensions() except that <i>nid</i> is used to identify the extensions attribute. This function must not be called more than once with the same <i>req</i> and <i>nid</i>.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>X509_REQ_get_extensions() returns a pointer to <b>STACK_OF(X509_EXTENSION)</b> or NULL on error.</p>

<p>X509_REQ_add_extensions() and X509_REQ_add_extensions_nid() return 1 on success, 0 on error.</p>
